[OSM-dev] Rendering of TIGER data (and a new version of the scripts)

[Dave Hansen]

First of all, I have a new version of the conversion scripts, fixing
some bugs, but no complete show stoppers.

I've uploaded Hood River County, Oregon, and it was in the last planet
dump.  It is now appearing on the map:

	http://www.openstreetmap.org/index.html?lat=45.7090343713106&lon=-121.52713777738832&zoom=16

I quite like how it looks.

The entire US is still available for download here:

But, I'll be replacing those over the next few days as I re-run with the
latest version.

Changelog from v0.5:
- There was an occasional glitch in the data, mostly with long forest
  service roads where it looked like the segments weren't put in place. 
  I found the cause:
	rt1_record.rt2_records.sort! do |a,b| a[:rtsq] <=> b[:rtsq] end
  That was sorting a number *ALPHABETICALLY*, and would assemble some of
  the TIGER ways into OSM ways in the wrong order
- Stopped outputting ways with no segments.  This was a byproduct of not
  fully deleting ways when they were coalesced into another.  I also
  released an extension to the JOSM validator plugin to find and fix
  these, just in case you have them in a data file. 
- slightly reduced memory footprint, again
- will hopefully skip over missing (but non-critical) TIGER shapefiles
- Don't feed "raw_tags" into the tags_to_feature_type() function,
  because the raw ones aren't real strings
